Interesting, so it likely isn't buggy.
Could you give lspci -v -v or so (to let us see chipset and revisions)?
Oh wait, you already did:

We need to enhance current kernel to whitelist this chipset revision somehow. Or at least put a note there that this revision is ok, too (to wait some more time for further evidence/revisions to appear).

You mean e.g. the clock=tsc boot parameter?
